Sure that would do the trick.
But i wanted to put on shoes for those in the community who may want to once in a while attend some of these calls without having setup calendars.
In other words, i would like us to adopt such a habit of sending out notifications like, "Hey, the openmrs ??? meeting is happening in the next 5 or so minutes".
This would even help those who once in a while get mixed up with time zone issues or day light savings changes.
